OF EL PASO, TEXAS.

DEVICE FOR PREVENTING OVERFLOW OF" TANKS.

Application filed February 16, 1915. Serial No. 8,607.

To all whom it may concern:

Be it known that 1, PAUL H. LOGAN, a citizen of the United States, residing at El Paso, in the county of El Paso and State of Texas, have invented a new and useful Device for Preventing Overflow of Tanks, of which the following is a specification.

The device forming the subject matter of this application is adapted to be employed for preventing the repeated discharge of the contents of a flush tank should the float conthe flush tank prove inoperative for any reason.

The invention aims to provide anovel device, actuated by the contents of the flush tank, for-closing a valve in the supply .p pe when the contents of the flush tank rises above a predetermined-level.

It is within the scope of the disclosure to improve generally and to enhance the utility of devices of that typeto which the present invention appertains.

Withthe above and other objects in view whichwill appear as the description protheinvention resides in the combinaceeds parts and in the detion and arrangement oi tails of construction hereinafter described and claimed. Changes can be made within the scope of what is claimed without depart ing from the spirit of the inventio In the accompanying drawing :Figure 1 is a sectional view in which sundry parts appear in elevation, portions being broken away; Fig. 2 is a top plan of the movable receptacle which actuates the valve in the pipe; Fig. 3 is a longitudinal sectional view of the movably mounted receptacle, the con,- nection between the receptacle and the valve in the supply pipe appearing in elevation.

In the accompanying drawings, the numeral 1 indicates a receptacle of any sort such as a water closet bowl.

The numeral 2 indicates a flush tank supported in any manner as indicated at 3. The discharge or flush pipe which leads from the tank 2 to the water closet bowl 1 or other receptacle is denoted by the numeral 4. Thenumeral 5 indicates a vertically movable siphon coacting with the upper end of the fiush pipe 4, the siphon- 5 being controlled by means of a lever 6 fulcrumedintermediate its ends on a support 7 and ordinarily actuated by means of a flexible element 8.

A supply pipe 9 communicates with the Patented Apr. 4, 1916.

tank-2 and at the upper end of the pipe 9' i there is a valve 10 controlled by a lever 11 actuated by a float 12.

The foregoing structural details are common and well known in the art, and no novelty is claimed for them, saving in so far as they may cooperatewith sundry parts to be described in detail hereinafter.

the valve 10 which cOn- If from any cause, trols the supply pipe 9 becomes inoperative, the water rises in the tank 2 to the crown of the siphon 5, and thereupon the contents of the tank are discharged through the pipe 4, this operation continuing repeatedly, with obvious Waste. The continued discharge through the supply pipe 9 into the tank 2 may take place when there is an unduly heavy pressure in the pipe 9, if the float .12 becomes detached from the lever 11, it the lever 11- becomes accidentally detached from the valve 10, and from other causes comprehended by those skilled in the art. In view of the foregoing, it will now be understood that the object of the present invention is to prevent a repeated discharge 7 of the contents of the tank 2 under the circumstances above pointed out.

In the resent embodiment of the invention, vertically spaced brackets 14 are attached to one end of the flush tank 2, the brackets 1 1 being connected by upright guides 15, the brackets and the elements 15 co'acting to form a which is mounted to-reciprocate a receptacle 17. The receptacle 17 is entirely closed, saving for a pet cock 1 9 in the bottom of the receptacle, and receptacle which receives the depending portion of an'angular pipe 16,:-"t'he pipe '16 entering the tank 2 slightly below the crown of the siphon 5. The receptacle 17 is mounted to reciprocate in the guides 15 an'dupon the depending-end of the pipe 16. The receptacle 17 is provided with a depending ear 20 to which is pivoted as shown at 20*, the upper end of alongitudinally extensible connection which may be a turnbuckle 21, the

lower end of the turn buckle being pivoted as longitudinally extensible lever may be held guiding structure ina gl'and 18 in the; top of the.

at adjusted lengths by means of a set screw 25 threaded into the stem and engaging the slide Ii through any ofthe causes hereinbetore mentimied, the water rises to an undue level within the flush tank 2. the water will flow by way of the pipe 16 into the receptacle l7 and the latter will be depressed, the bottom of the receptacle 17 moving away from the lower end of the pipe 16, and the air in the receptacle bubbling away through the pipe 16. \Vhcn the receptacle 17 descends, the

valve 2t will be actuated through the medium of the lever 23-49 and the connection 21, the valve being moved to a closed position, so as to cut off the supply pipe 9. 'lhereupon, no more water will enter the flush tank 2 by way of the pipe 9 and a repeated siphoning out of the flush tank 2, with consequent waste, will be avoided. In order to reset the structure, the pet cock 19 is opened and the receptacle 17 is drained, whereupon the receptacle may be elevated to the position shown in Fig. 1, the valve 2 1 ordinarily operating with suliicient friction to hold the receptacle in its raised position. Obviously, by means of the slide 22 and the stem together with the longitudinally extensil'ile turn buckle connection 21, the

throw of the valve 2% may be regulated, and

at the same time, the closing of the valve 24 when the receptacle 17 is depressed may be assured.

Having thus described the invention, what is cla med is 1. Ina device of the class described, a tank; an outletfor the tank; means for controlling the outlet; a supply pipe for the tank; a movable receptacle located eXteriorly of the tank; means for conducting the contents of the tank into the receptacle after the contents of the tank has risen to a predetermined level; a valve'in the supply pipe; and an operative connection between the receptacle and the valve and disposed exteriorly of the tank.

2. In a device of the class described, a. tank; an outlet for the tank; means for controlling the outlet; a supply pipe for the tank; a conduit leading from the tank; a receptacle mounted to slide upon the conduit and adapted to receive the contents of the tank through the conduit ;'a valve in the supply pipe; and a connection between the receptacle and the valve.

3. In a device of the class described, a

tank; an outlet for the tank; a vertically movable siphon controlling the outlet; means for operating the siphon; a supply pipe for the tank; a valve in the supply pipe; float controlled means for operating the valve; a guiding structure carried by the tank; a receptacle mounted t reciprocate in the guiding structure; an angular pipe, one end of which enters the receptacle, the other end of which enters the tank; a second valve in the supply pipe; a longitudinally extensible lever united with the valve; and a longitudinally extensible connection uniting the lever with the receptacle.

In testimony that I claim the foregoing as my own, I have hereto aiiixed my signature in the presence of two witnesses.

PAUL H.- LOGAN.
